Abstract A combined heat and mass transfer in laminar forced convection flow in a rectangular venturi tube have been numerically simulated. A
transformation has been used to transform the irregular profile of the venturi walls into a straight line. Transfers equations are solved using finite
volume method, Gauss and Thomas algorithms. The influences of venturi effect, inlet Reynolds number and venturi diameter ratio on the heat and
mass transfer are discussed in detail. Results presented as pressure gradient, Nusselt and Sherwood numbers profiles, velocity patterns and isotherms
show that the throat play an important role on the heat an mass transfer… More >
